    As compared to yamaha, denon or the like?I have a Sony STR-DB930 and a Yamaha HTR-5280 and you can leave the Yammy on all day and it's barely warm but the Sony is hot enough to fry an egg just after two hours or so.They both are out in the open with no abstruction of the vents,and both recievers impeadence switch's are set to 4 ohms.Is it just the way the sony amp is designed or what?Any help would be appreciated.Thanks and cheers..

    just think, all that heat is just wasted energy!

    Usually the higher the class of an amp, eg A, B, or C, the less efficient it.

    Well, i think thats what i remember...?

    Could be because of no cooling fan

    I hear people moaning about Denons running very hot. My Sony 940 seems fine, does get hot though. I guess they are all designed to work at those temperatures.

    Just think, in the winter you can just turn up the volume and save on central heating costs.
